+API Microversioning
+-------------------
+We have to provide backward compatibility by adding API microversioning since
+Watcher get new resources and their attributes during development cycles.
+
+Watcher Planner Selector
+------------------------
+This component is responsible for selecting an appropriate `planner`_ for a
+given `strategy`_ depending on several factors (e.g list of `actions`_ used by
+the strategy or user request)
+
+Define grammar for workload characterization
+--------------------------------------------
+As we run several workloads in a cloud, we should be able to characterize
+such workloads as input to watcher for ensuring Application QoS, placements
+and consolidation. An example of workload characterization is a weighted
+combination of CPU, Memory or any other resource attributes like High IOPs,
+Network latency etc.
+
+Bare metal node N+1 redundancy
+------------------------------
+This proposes high availability/reliability feature to support Bare Metal Node
+N+1 Redundancy based on data from Ceilometer.
+
+When a bare metal node is failed due to hardware problem or is likely to be
+failed due to a sign of hardware failure, this function allows to switch over
+the node safely to another bare metal node in short time if the failed node is
+booted from a volume.
+
+Ironic notifications for bare metal DM
+--------------------------------------
+Update the bare metal data model by ironic notifications
+
+Update Data Model by Nova notifications
+---------------------------------------
+Watcher consumes Nova notifications to update its Data Model. So far only
+several notifications are used, there are many notifications need to be
+consider, such as instance poweron/poweroff, they all change the state of
+instance. Watcher should update the state of instance in the Data Model by
+consuming appropriate Nova notifications that influence the state of instance
+or compute.
+
+Display Data Model of specified Audit
+-------------------------------------
+This blueprint will allow to display structure of Audit's Data Model. Data
+Model stucture should be useful for operators who would like to know the set
+of resources, which are also known as `scope`_, that are used by Audit. The
+response can be represent as table in case of CLI and as graph model in case of
+Watcher Dashboard.
+
+Add the start/end time for CONTINUOUS audit
+-------------------------------------------
+Currently we can only set audit execution interval, but we can not set audit
+start and end time. We need to increase the `audit`_ start and end time for
+CONTINUOUS audit.
+
+Audit scoper for baremetal data model
+-------------------------------------
+Since baremetal data model was added, we need audit scoper for baremetal
+data model as compute data model has.
+
+Enhance watcher Applier engine
+------------------------------
+Currently watcher's Applier can only run actions one by one or parallel.
+We need to decide whether the next action is executed based on the result of
+the previous action, so we need to enhance the applier.
